COV Saca Wastewater Treatment Plant, Košice, Slovakia

COV Saca is an advanced wastewater treatment plant located in the Šaca district of Košice, Slovakia. Serving a population of 2,953, it is a small-scale facility within the Košický kraj region. The plant is part of the municipal wastewater infrastructure for the city of Košice, the second-largest city in Slovakia. The plant employs advanced treatment processes, ensuring high-quality effluent. With a designed capacity of 8,411 m³/day and an actual discharge volume of 604.34 m³/day, it operates well below its capacity. As a Slovak facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels for agglomerations of this size. The treated wastewater is discharged into the local watershed, which ultimately drains into the Hornád River and then the Tisa River basin, flowing into the Black Sea. The plant plays a key role in protecting the water quality of these downstream water bodies and supporting the ecological health of the region.

The plant discharges into the Hornád River catchment, part of the Tisa River basin that flows into the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The advanced treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication.
